Keyboard input
We now have touch and mouse input, but many players also use desktop or laptop machines where playing with a mouse isn't the best experience. Thankfully they all have a keyboard, which will let us add some simple controls to mimic the touch controls that we currently have.
Just like the pointer system, keyboard events are raised by the CoreWindow object that we have in the GameApplication class. To begin, create some event handlers like you did for the OnPointerReleased handler, but use the KeyEventArgs instead of PointerEventArgs.
Add the following code in the GameApplication.h file:
void OnKeyDown(Windows::UI::Core::CoreWindow^ sender, Windows::UI::Core::KeyEventArgs^ args); void OnKeyUp(Windows::UI::Core::CoreWindow^ sender, Windows::UI::Core::KeyEventArgs^ args);
Now add the code that follows in the GameApplication.cpp file:
void GameApplication::OnKeyDown(Windows::UI::Core::CoreWindow^ sender, Windows::UI::Core::KeyEventArgs^ args)
{
m_renderer->KeyDown(args->...
